List the general guidelines for constructing pie charts.

Answers will vary. Pie charts, like segmented charts and area charts, show how the parts of a whole are distributed. Here are some general guidelines for constructing pie charts:
a. Position the largest slice or the slice to be emphasized at the 12 o'clock position. Working clockwise, place the other slices in descending order of size or some other logical order of presentation.
b. Label each slice and include information about the quantitative size (percentage, dollars, etc.) of each slice. If you are unable to attractively place the appropriate labeling information beside each slice, use a legend to identify each slice.
c. Draw attention to one or more slices for desired emphasis. Special effects include exploding the slice(s) to be emphasized (i.e., removing it from immediate contact with the pie) or displaying or printing only the slice(s) to be emphasized.
d. Avoid using 3D-type formatting that makes values more difficult to distinguish.
